the style that you choose to study,i studied ti kwon do when i was younger and decided it was to agressive for me,with bad knees and all if i ever took up any martial arts program again it would be kempo a lot less kicking involved,as with any style you choose you have to be a serious student not just weekends,it takes a lot of dedication on a students part,to me one style is as good as the next,any training that can get you out of a situation with little or no injury is good,but remember always martial arts is for self protection only.
